The conductivity of aluminum is about 61.2% to 62.0% of that of copper. Therefore, an aluminum conductor must have a cross-sectional area about 1.6 times that of a copper conductor to have the equivalent DC resistance. This difference in area is approximately equal to two American wire gauge (AWG) sizes.
鋁的導電率大約是銅的61.2%至62%, 因此, 鋁導體必須大約為銅導體的1.6倍的截面面積來得到相同的直流電阻. 該面積的差異大約等於二個美國線規(guī)(AWG)的差異. (學習學習)
